I think you are right about the prevalence of GCC 2.95. Michael Chastain has made the same sorts of comments. But dropping the kludge in question is not the same as dropping GCC 2.95 support. The kludge is a fix for a specific GCC 2.95 bug, and if I remember right, GDB had been in widespread use with that compiler for several releases before the bug got fixed. I think GCC 2.95 defaulted to STABS on the i386 anyway. (I apologize for being too lazy to search the archives to verify all this.)
